摘要:
The present invention concerns D-deoxygalactonojirimycin derivatives shown below. These compounds display an increased inhibitory potency towards GCS, and/or an increased inhibitory potency towards GBA2, and/or a decreased inhibitory potency towards GBA1, relative to known deoxynojirimycin derivatives of the same D -galacto configuration. Therefore, compounds of the present invention are effective in the treatment of diseases which are associated with an irregular level of cytosolic or lysosomal glucosylceramide and/or higher glycosphingolipids, such as a lysosomal storage disorder, such as Gaucher disease, Fabry disease, Tay-Sachs disease, Sandhoff disease, GM1 gangliosidosis, Sialidosis, Niemann Pick disease type C and AMRF, or a symptom of one of the diseases collectively classed as metabolic syndrome, such as obesity, insulin resistance, hyperlipidemia, hypercholesterolemia, polycystic kidney disease, type II diabetes and chronic inflammation, or a neurodenegerative disorder, such as Parkinson disease or Lewy-body dementia.
摘要:
Deoxynojirimycin and deoxygalactonojirimycin derivatives according to the present invention are N-alkylated D-galacto, D-gluco- or L-ido-deoxynojirimycin with a linear methyloxypentyl group bearing various sidegroups and a non-fused bicyclic aromatic group (“X”) on the methyloxy-carbon. These compounds display an increased inhibitory potency towards GCS, and/or an increased inhibitory potency towards GBA2, and/or a decreased inhibitory potency towards GBA1, relative to known deoxynojirimycin derivatives of the same (D-gluco, L-ido or D-galacto) configuration. Therefore, compounds of the present invention are effective in the treatment of diseases which are associated with an irregular level of cytosolic or lysosomal glucosylceramide and/or higher glycosphingolipids, such as a lysosomal storage disorder, such as Gaucher disease, Fabry disease, Tay-Sachs disease, Sandhoff disease, GM1 gangliosidosis, Sialidosis, Niemann Pick disease type C and AMRF, or a symptom of one of the diseases collectively classed as metabolic syndrome, such as obesity, insulin resistance, hyperlipidemia, hypercholesterolemia, polycystic kidney disease, type II diabetes and chronic inflammation, or a neurodenegerative disorder, such as Parkinson disease or Lewy-body dementia.

摘要:
An activity based probe (ABP) comprising a glycosidase inhibitor, and a detection-group. The ABPs of the inventions are used for diagnosing storage disorder for screening of compounds suitable for preventing and/or treating a storage disorder, for monitoring of therapeutic enzymes for lysosomal storage disorders, and for ultra- sensitive visualization of glycosidase-fusion proteins in molecular imaging.
摘要:
The present invention discloses a therapeutic target for the treatment of cyst ic fibrosis. It was found that inhibition of non-lysosomal glucosylceramidase (GBA2) sufficiently restores chloride current in cells from CF patients carrying the common delF508-CFTR mutation. With the catalytic centre (4) of the enzyme positioned on top of the membrane bilayer face particularly potent inhibitors are found in deoxynojirimycin derivatives having a group that is capable of inserting in the membrane bilayer.
摘要:
The present invention relates to compounds according to formula (I) : wherein R2 is absent or a linking moiety and R3 is selected from the group consisting of anti- inflammatory agents and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising compounds of formula (I) and the use of these pharmaceutical compositions for the treatment or prophylaxis of chronic inflammatory diseases, in particular those that are caused by chronically activated macrophages. The chronic inflammatory disease is in particular atherosclerosis, (rheumatoid) arthritis, an (auto) immune disease.or sarcoidosis.

摘要:
The invention provides means and methods for detecting a glycosylated metabolite in a sample comprising adding to the sample a compound comprising a labelled glycosyl group coupled via an O-glycosidic bond to an aglycon with a specific structural formula wherein the glycosyl group comprises at least one isotope and/or a side chain being a label for detection, and wherein the sample is screened for the presence of a glycosylated metabolite with the glycosyl group other than a glucosylceramide. The invention further provides a method of treating a disorder caused by accumulation of a glycosylated metabolite other than glucosylceramide in a subject comprising administering to the subject in need thereof a therapeutically effective amount of a glucosylceramide synthase (GCS) inhibitor.
